# Camel-Kafka-connector Infinispan Source With Authentication

This is an example for Camel-Kafka-connector Infinispan Source With Authentication

## Standalone

### What is needed

- An Infinispan instance

### Setting up Infinispan

As first step you need to download the Infinispan Server with version 12.0.0.Final.

You can now start your server

```
> $INFINISPAN_HOME/bin/server.sh
bin/server.sh

```

So, you'll need to run

```
> $INFINISPAN_HOME/bin/cli.sh user create admin -p "password"
> $INFINISPAN_HOME/bin/cli.sh
[disconnected]> connect
Username: admin
Password: ********
[ghost-35169@cluster//containers/default]> create cache --template=org.infinispan.DIST_SYNC mycache
[ghost-35169@cluster//containers/default]> describe caches/mycache
{
  "distributed-cache" : {
    "mode" : "SYNC",
    "remote-timeout" : 17500,
    "state-transfer" : {
      "timeout" : 60000
    },
    "locking" : {
      "concurrency-level" : 1000,
      "acquire-timeout" : 15000,
      "striping" : false
    },
    "statistics" : true
  }
}

```

It's important to add encoding to your cache configuration, otherwise consuming events won't work.
You'll need to:

- Edit $INFINISPAN_HOME/server/data/caches.xml

and add the encoding section in the configuration

```
<?xml version="1.0" ?>

<infinispan xmlns="urn:infinispan:config:12.0">
    <cache-container>
        <distributed-cache mode="SYNC" remote-timeout="17500" name="mycache" statistics="true">
            <encoding>
                <key media-type="text/plain; charset=UTF-8"/>
                <value media-type="text/plain; charset=UTF-8"/>
            </encoding>
            <locking concurrency-level="1000" acquire-timeout="15000" striping="false"/>
            <state-transfer timeout="60000"/>
        </distributed-cache>
    </cache-container></infinispan>
```

Now you should be able to run this example.

### Running Kafka

```
$KAFKA_HOME/bin/zookeeper-server-start.sh $KAFKA_HOME/config/zookeeper.properties
$KAFKA_HOME/bin/kafka-server-start.sh $KAFKA_HOME/config/server.properties
$KAFKA_HOME/bin/kafka-topics.sh --create --bootstrap-server localhost:9092 --replication-factor 1 --partitions 1 --topic mytopic
```

## Setting up the needed bits and running the example

You'll need to setup the plugin.path property in your kafka

Open the `$KAFKA_HOME/config/connect-standalone.properties`

and set the `plugin.path` property to your choosen location

In this example we'll use `/home/oscerd/connectors/`

```
> cd /home/oscerd/connectors/
> wget https://repo1.maven.org/maven2/org/apache/camel/kafkaconnector/camel-infinispan-kafka-connector/0.10.0/camel-infinispan-kafka-connector-0.10.0-package.tar.gz
> untar.gz camel-infinispan-kafka-connector-0.10.0-package.tar.gz
```

Now it's time to setup the connectors

Open the Infinispan source configuration file

```
name=CamelInfinispanSourceConnector
connector.class=org.apache.camel.kafkaconnector.infinispan.CamelInfinispanSourceConnector
key.converter=org.apache.kafka.connect.storage.StringConverter
value.converter=org.apache.kafka.connect.converters.ByteArrayConverter

topics=mytopic

camel.source.endpoint.hosts=localhost
camel.source.path.cacheName=mycache
camel.source.endpoint.eventTypes=CLIENT_CACHE_ENTRY_CREATED
camel.component.infinispan.secure=true
camel.source.endpoint.username=admin
camel.component.infinispan.password=password
camel.component.infinispan.saslMechanism=DIGEST-MD5
camel.component.infinispan.securityRealm=default
camel.component.infinispan.securityServerName=infinispan
```

Now you can run the example

```
$KAFKA_HOME/bin/connect-standalone.sh $KAFKA_HOME/config/connect-standalone.properties config/CamelInfinispanSourceConnector.properties
```

On a different terminal run your cli.sh from the Infinispan server

```
> $INFINISPAN_HOME/bin/cli.sh
[disconnected]> connect
Username: admin
Password: ********
[ghost-43981@cluster//containers/default]> cache mycache
[ghost-43981@cluster//containers/default/caches/mycache]> put test test
```

In another terminal, using kafkacat, you should be able to see the headers.

```
> kafkacat -b localhost:9092 -t mytopic -C -f 'Headers: %h\n'

Headers: CamelHeader.CamelInfinispanCacheName=mycache,CamelHeader.CamelInfinispanEventType=CLIENT_CACHE_ENTRY_CREATED,CamelHeader.CamelInfinispanIsPre=false,CamelHeader.CamelInfinispanKey=test,CamelProperty.CamelToEndpoint=direct://end?pollingConsumerBlockTimeout=0&pollingConsumerBlockWhenFull=true&pollingConsumerQueueSize=1000
% Reached end of topic mytopic [0] at offset 1
